Ukuphathwa kwamanzi emvula kuyisici esibalulekile sokuhlela amadolobha kanye nokuvikelwa kwemvelo. Njengoba izindawo zasemadolobheni ziqhubeka nokukhula, umthelela wokugeleza kwamanzi emvula ekhwalithini yamanzi kanye nemvelo uye waba mkhulu kakhulu. Ukuze uphathe kahle amanzi emvula, kubalulekile ukuba nedatha yokugeleza kanye nesivinini enembile nethembekile. Yilapho amamitha okugeleza esivinini sendawo edlala khona indima ebalulekile.
Ama-flowmeter ejubane lendawo ayizinto ezikhethekile ezenzelwe ukukala ukugeleza kwamanzi emvula eziteshini ezivulekile, ama-culvert kanye nemisele yamanzi angcolile. Asebenzisa izimiso zama-hydraulic kanye ne-fluid dynamics ukubala ukugeleza ngokusekelwe endaweni enqamulayo kanye nejubane lamanzi. Lolu lwazi lubalulekile ekuqondeni inani kanye nesivinini sokugeleza kwamanzi emvula, okubalulekile ekwakheni izinhlelo zokuphatha amanzi emvula ezisebenzayo.
Enye yezinzuzo eziyinhloko zamamitha okugeleza kwejubane lobuso yikhono lawo lokuhlinzeka ngedatha yesikhathi sangempela ngokugeleza kanye nejubane. Lokhu kubaluleke kakhulu ngesikhathi seziphepho, lapho ivolumu kanye nesivinini seziphepho kungashintsha ngokushesha. Ngokuqhubeka nokuqapha amazinga okugeleza, amamitha okugeleza kwejubane lendawo avumela iziphathimandla ukuthi zenze izinqumo ezinolwazi mayelana nokuvikelwa kwezikhukhula, ukuvimbela ukuguguleka komhlaba kanye nokuphathwa kwekhwalithi yamanzi.
Ngaphezu kokuqapha ngesikhathi sangempela, amamitha okugeleza kwejubane lendawo anikeza izinzuzo zokunemba nokuthembeka. Izindlela zokulinganisa ukugeleza zendabuko, njengezindonga zomfula kanye nama-flume, zivame ukwehluleka ukunikeza idatha enembile, ikakhulukazi ngesikhathi semicimbi yokugeleza okuphezulu. Amamitha okugeleza kwejubane lendawo, ngakolunye uhlangothi, ayakwazi ukulinganisa amazinga okugeleza ahlukahlukene ngokunemba okuphezulu, okwenza abe ithuluzi eliwusizo lokuphathwa kwamanzi emvula.
Ngaphezu kwalokho, amamitha okugeleza kwejubane lendawo afakwe ubuchwepheshe obuthuthukisiwe obuvumela ukuqoqwa nokuqapha idatha ekude. Lokhu kusho ukuthi iziphathimandla zingafinyelela idatha yethrafikhi ezindaweni eziningi ngaphandle kwesidingo sokungenelela komuntu. Ngokuhlanganisa amamitha okugeleza kwejubane lendawo ezinhlelweni zokuqapha inethiwekhi, ukuqonda okuphelele kwezindlela zamanzi emvula ezindaweni zasemadolobheni kungafinyelelwa.
Idatha eqoqwe ngamamitha okugeleza kwejubane lendawo ibalulekile hhayi nje ekuphathweni kwamanzi emvula amanje, kodwa futhi nasekuhleleni kwesikhathi esizayo. Ngokuhlaziya idatha yokugeleza komlando, iziphathimandla zingabona izitayela namaphethini okugeleza kwamanzi emvula ukuze zinikeze ulwazi ngokuklama nokusetshenziswa kwamasu okuphatha amanzi emvula esikhathi eside. Le ndlela yokuqapha ibalulekile ekunciphiseni imiphumela yokukhula kwamadolobha ekhwalithini yamanzi kanye nemvelo.
Ngamafuphi, ama-flowmeter esivinini sendawo adlala indima ebalulekile ekuqapheni nasekuphatheni amanzi emvula ezindaweni zasemadolobheni. Amandla awo okuhlinzeka ngedatha yesikhathi sangempela, enembile nethembekile awenza abe ithuluzi elibalulekile ezikhulwini nasezinhlanganweni zemvelo. Ngokusebenzisa amakhono amamitha okugeleza esivinini sendawo, amasu asebenzayo angathuthukiswa ukunciphisa imiphumela yokugeleza kwamanzi emvula nokuvikela impilo yemigwaqo yamanzi.
